JOIN USDiCaprio, who is in Sydney to film 'The Great Gatsby', is said to have had regular visits from 21-year-old Crawford, a former Australia's Next Top Model contestant, at his hotel, the Daily Telegraph reported.
"It's been going on about two weeks. He texts her when he wants to see her and they hook up a few times a week. They've mostly been meeting up during the week. He does other things on weekends. She's been going to his hotel to visit but he is too smart to be seen with her in public," a source told the newspaper.
It is likely that Crawford may have been behind the end of DiCaprio's five-month-old romance with Lively.
Crawford, however, has denied dating the 'Titanic' star but described him as a "lovely, lovely guy".
"We have a lot of mutual friends and he seems really nice. We're just friends."
DiCaprio has a history of dating models and his previous flames include Gisele Bundchen and Bar Refaeli.
